All of the information about buying the book for this course stresses that you will need a version that includes access to a program called "LaunchPad."
I am changing that.
The start of class is about a week away, and LaunchPad has some major technical problems, so I'm backing out of that requirement. You won't see LaunchPad on the syllabus.
The textbook version with the LaunchPad access card costs the same as the one without, so you haven't wasted any money, and if you buy the card separately, you should be able to return it to the bookstore for credit.
Don't throw that card away, though. If the publisher fixes things, we might actually use the program. It has a lot going for it if the students can get to it.
